Manufacturing Quality Control of 2-METHYLSTYRENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID | Quantitative separation and detection based on retention time and peak area relative to a certified reference standard. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a controlled anhydrous medium. |
| Acid Number | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and potentiometric or visual endpoint detection. |
| Color (APHA) | Visual Comparison or Spectrophotometry (APHA scale) | Comparison of sample color intensity against platinum-cobalt standard solutions at 455 nm wavelength. |
| Density at 20 C | Digital Density Meter (Oscillating U-tube) | Measurement of sample density via resonant frequency shift of a vibrating U-shaped tube filled with the liquid. |
| Refractive Index at 20 C | Refractometry | Determination of refractive index by measuring the critical angle of total internal reflection at the prism-sample interface. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of a known volume under controlled conditions followed by weighing of non-volatile residue. |
| Peroxide Value | Iodometric Titration | Oxidation of potassium iodide by peroxides to liberate iodine, quantified by sodium thiosulfate titration. |
| Total Chloride Content | Ion Chromatography (IC) | Separation of chloride ions on an anion-exchange column with conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal content by measuring absorption of characteristic atomic spectral lines after atomization in a flame or graphite furnace. |
| Aldehyde Impurities | HPLC with UV Detection | Separation and quantification of aldehydes using reversed-phase chromatography and UV absorbance at 270 nm. |
| Inhibitor (e.g., TBC) Content | GC-MS or HPLC-UV | Identification and quantification of polymerization inhibitors based on retention time/mass spectrum or UV response relative to calibration standards. |
